- The Avid codecs allow you to select the color space (709 or RGB) and I believe that is why the RGB-YUV conversions are apparently handled better by the Avid codecs.
- Something to keep in mind when embarking on projects that may require material to meander into the RGB space.
- The big surprise for me was the performance of Avids DNxHD 36 codec. (Only) 3.5% of the original file size
and look at how amazing it did.
- Since its a progressive-only codec, I couldnt run it on my second set of tests.

- 1080i/50 is 1920 x 1080, as is DNxHD 185 and DNxHD 120
- Throughput: 185Mb/sec for DNX185 = 23MB/sec.

- DNxHD 36 is great..BUT (as of 2007) only works in 1080p/23.98. Why not 720p/59.94 or 1080i/59.94 ?? Answer: The format was created for the film-offline-HD crowd, thus the limited 1080p support.
